## New ACTIONS
|
|
|
|
|
|
- **ACTION A11**: To proceed with the CERN review, we would need the following:
|
|
|
- **new models of both backplanes and of the front panel** from Michal
|
|
|
- models of **off-the-shelf power supplies**
|
|
|
- **models of system and peripheral boards** including new provided models/front panels
|
|
|
- **roof/feet** consolidation (see **ACTION A4)**
|
|
|
|
|
|
- **ACTION A12**: **BOM spreadsheet** hidden items are the screws; it s not clear yet which ones are provided with the Schroff parts; will confirm after the first prototype is built.
|
|
|
---
|
|
|
- **ACTION B4**: Ask Michal to **move IDC connectors** in main backplane more to the edge for the RTM separator; 1mm more would be great
|
|
|
|
|
|
## ACTIONS to be followed up
|
|
|
|
|
|
- **ACTION A4:** **Roof and feet** design:
|
|
|
- **Feet**: should we add more feet at the center of the crate for better weight distribution?
|
|
|
- **Roof**: we would need to see the model with the roof risen to confirm that it would not interfere with connectors on the front panels and that it would also protect the back from water drops. Please also have a look at this better picture of another crate installed in the LHC (ignore the red circles, they came with this picture I found); here the space above and below the crate is used to pass cabling, which is also probable is our case. <br>

|
|
|
|
|
|
- **ACTION A6:** 3-D printed **cable holders** have been added; there are also these spring-type ones, but they do not appear correctly in the 3D model, they seem like tubes. Could this be corrected in the 3D model?
|
|
|
|
|
|
- **ACTION A7:** Autodesk model browser **descriptive names** is very time consuming and does not make sense to do it now that some parts are uncertain; for now we leave them like that and Kuba/Michal confirmed that in the end of the project they will be ok
|
|
|
|
|
|
- **ACTION A8:** Ask Schroff if the **following colors or similar** are available in metallic paint: <br>
|
|
|
**RAL5051, RAL4003, RAL9010**
|
|
|
|
|
|
Note that Schroff has confirmed the availability of **6HP RTM** front panels; min order 25 and price 10eur/pc, which is expensive, but there is availability; the front panels for the front modules are more available and cheaper.
|
|
|
|
|
|
|
|
|
- **ACTION A9:** Mikolaj has contacted **Anna for the BOM** purchase for the first prototype; he will follow up
|
|
|
|
|
|
----
|
|
|
- **ACTION B3:** CERN to check which **materials** should not be installed in the tunnel and confirm that plastics: PLA/ ABS/ photopolymeric raisins are ok
|
|
|
|
|
|
|
|
|
## ACTIONS completed
|
|
|
- **ACTION A2:** **Metal plate** under design; to be delivered next week
|
|
|
- **ACTION A10:** Tentative **BOM** to be provided (for Schroff, CERN-stores)
|
|
|

## New ACTIONS
|
|
|
|
|
|
- **ACTION A10:** Tentative **BOM** to be provided (for Schroff, CERN-stores)
|
|
|
----> Done
|
|
|
----
|
|
|
- **ACTION B3:** CERN to check which **materials** should not be installed in the tunnel and confirm that plastics: PLA/ ABS/ photopolymeric raisins are ok
|
|
|
----> Ongoing
|
|
|
|
|
|
|
|
|
## ACTIONS to be followed up
|
|
|
|
|
|
- **ACTION A2:** **Metal plate** under design; to be delivered next week
|
|
|
----> Done; to ask Michal to move IDCs
|
|
|
|
|
|
- **ACTION A4:** **Roof** design ongoing; **feet** added on the perforated bottom panel; cheap solution; 6 to 10 feet added to hold all the weight.
|
|
|
Note that the perforated panels are anyway customized (not off-the-shelf) for the cutouts at 160 and 220mm
|
|
|
----> Ongoing
|
|
|
|
|
|
- **ACTION A6:** Please have a look at the WR-switch **cable holder**
|
|
|
![cable-holder](uploads/fbfada9cf439fee71f6b2848408be58f/cable-holder.jpg)
|
|
|
----> These cable holders are actually being used; the model is not clear
|
|
|
|
|
|
- **ACTION A7:** Ongoing Autodesk model browser **descriptive names**
|
|
|
----> Will be done at the end of the project once the list is finalised
|
|
|
|
|
|
- **ACTION A8:** Waiting for Schroff input on **colors and 6HP RTM** front panels
|
|
|
----> RTM front panels available; CERN to provide colors
|
|
|
|
|
|
- **ACTION A9:** **Anna** is back from holidays on Monday and will follow-up with Erik
|
|
|
|
|
|
----> On going
